torque multiplier - any advice/recommendations

[FlipFlopGriff]

Just found out about these so excited but some of them are 65:1 so for every 1Nm translates to 65Nm which is too much for what I need. Anyone got any recommendations in the budget range as it will only be occasional use - not chinese copies. Thanks.

What are you going from and to, Nm wise?

[FlipFlopGriff]

Up to 300Nm at the moment. Its for a mid 1990's American RV - struggled to get the leaf spring axle bolts off (410Nm impact wrench and soaked in penetrating fluid - none of the 8 moved) so looking to loosen and tighten a bit easier. Wheel nuts are next - tried removing a few - again won't budge.
Just need a 3:1, 4:1 or similar as I'm not building a tanker.

Heat and a big bar should solve the issue!

Thats not high enough to start messing about with torque multipliers. Good torque multipliers tend to big and heavy, they don't really lend themselves small spaces or un doing rounded bolts.

I'd just go with a bigger bar or getting hold of scaffolding pole or similar.

Also worth checking your wheel nuts aren't reverse threads, some big stuff like that is, my old LDV Convoy had reverse threads on the wheel nuts, feels very wrong going lefty tighty, righty loosey

Sounds like an excuse for a good 3/4” impact driver to me

Or as suggested a blowtorch and bigger breaker bar.

Wheel nuts aren't reverse threads as I can see the end of the thread, and it says left on the nut!!!! Also the leaf brackets are in a really awkward place hidden behind a dual wheel set up with brake pipes near them, working upside down and with little manoeuvring space so heat and big bars isn't really going to work. Those big multipliers are too industrial use for me.
Going to persevere with the battery angle grinder (it can pulse easily so safer than the electric one) for now taking it easy but may get a cheaper version. I'm only a DIY mechanic doing bits and bobs but enjoy the sense of achievement doing a job well and the bast4rd isn't beating me.

Be careful with an angle grinder and a leafspring...

I got a Sealey AK629 to deal with the rear hub nuts on my car. They need 340lb/ft or 460Nm.

I would take that marking to mean the nut is left hand thread. If you can see enough of the thread to confirm it's not then you're fine of course as there's no question but it sounded like you were using both points to confirm.

Is it also on the left hand side of the vehicle by any chance?
